This study investigated implications of viewing The Biggest Loser, NBC’s popular reality television show. Using online survey data collected from 613 participants, results suggest that exposure to the program is positively associated with perceived realism of the program, which in turn is positively associated with developing internal weight locus of control. Meanwhile, internal weight locus of control is positively associated with audience members’ exercise behavior, meaning the higher level of internal weight locus of control the audience members develop, the more likely they are to engage in physical exercise. This study offers evidence that health-related reality television might be a useful tool to influence audience members’ cognitions on health issues, which could potentially lead to healthy lifestyles. 相似文献

The objective of the present study was to investigate the effects of combined training without caloric restriction on inflammatory markers in overweight girls. Thirty-three girls (13–17 years) were assigned into overweight training (n = 17) or overweight control (n = 16) groups. Additionally, a normal-weight group (n = 15) was used as control for the baseline values. The combined training programme consisted of six resistance exercises (three sets of 6–10 repetitions at 60–70% 1 RM) followed by 30 min of aerobic exercise (walking/running) at 50–80% VO2peak, performed in the same 60 min session, 3 days/weeks, for 12 weeks. Body composition, dietary intake, aerobic fitness (VO2peak), muscular strength (1 RM), glycaemia, insulinemia, lipid profile and inflammatory markers (C-reactive protein, interleukin-6, tumour necrosis factor-alpha, interleukin-10, leptin, resistin and adiponectin) were measured before and after intervention. There was a significant decrease in body fat (P < 0.01) and increase in fat-free mass (P < 0.01), VO2peak (P < 0.01), 1 RM for leg press (P < 0.01) and bench press (P < 0.01) in the overweight training group. Concomitantly, this group presented significant decreases in serum concentrations of C-reactive protein (P < 0.05) and leptin (P < 0.05), as well as in insulin resistance (P < 0.05) after the experimental period. In conclusion, 12 weeks of combined training without caloric restriction reduced inflammatory markers associated with obesity in overweight girls. 相似文献

Diabetes Mellitus in obese and non-obese Indian individuals.AIMS: Effect of Obesity and insulin resistance on diabetic control.SETTINGS AND DESIGN: 50 each groups Diabetic individuals obese and non-obese.METHODS AND MATERIAL: On selected 50 each group diabetic patient and normal, following blood investigations has been performed—Plasma Glucose,
Glycohemoglobin and Serum Insulin.STATISTICAL ANALYSIS USED: Individuals patient’s results were analyzed and compared with the normal controls.RESULTS AND CONCLUSION: The changes in glycosylated haemoglobin are mainly proportional to the post lunch glucose level (r=0.773) (p<0.01) and not
correlated to circulating insulin or the body mass index. However the levels were higher in obese diabetes (Type I and II
both) than in non-obese. Mechanism of resistance in insulin receptor interactions due to obesity is well known. However, obesity
does not seem to affect directly glycosylated haemoglobin. Under such circumstances, the reduction of weight for a diabetic
person can improve sugar control by minimizing insulin resistance and thereby can improve glycosylated haemoglobin levels. 相似文献

福州市肥胖青少年减肥的调查研究 总被引：2，自引：0，他引：2
采用问卷法、访谈法、文献资料法、数理统计法等对福州市肥胖青少年的减肥行为及其相关因素进行了调查分析,主要结论:肥胖青少年对肥胖的认知极其有限和片面:综合运用多种方法进行减肥在肥胖青少年中具有普遍性;运动在控制体重和减肥中的重要作用得到了青少年的重视;肥胖青少年减肥效果较差;不良减肥行为的发生比例较高。建立加强肥胖与控制体重知识教育,宣传科学的减肥方式,预防和控制不良减肥行为的发生,旨在指导福州市肥胖青少年进行科学减肥,并为有关部门决策提供科学依据。 相似文献

文章采用人体测量学、生物电阻抗法对运动训练专业105名大学生进行体成分测量并探讨体脂含量和不同身体指数对运动员营养状况评价的相关性与一致性。研究结果表明：采用不同身体指数对运动员营养状况的判别结果不尽相同;BF%与各指数的相关性依次是：腰臀比〉肥胖度〉劳雷尔指数〉BMI〉克托莱指数。腰臀比、肥胖度、劳雷尔指数对运动员营养状况评判方面均有一定的应用价值。建议：在不具备体成分分析仪的情况下,可选用腰臀比、肥胖度、劳雷尔指数替代BF%、BMI指标,在应用时要注意特殊身材个体的处理,不宜使用克托莱指数判别运动员营养状况。 相似文献

东莞市中学生隐性肥胖的调查与对策 总被引：1，自引：0，他引：1
通过对广东省东莞市后街中学初、高中的新生进行测量分析,发现在初、高中生中肥胖和隐性肥胖男、女生部占有一定的比例,组织隐性肥胖者进行为期3个月的特定运动处方训练,证明通过运动处方训练,大部分隐性肥胖者可转为标准体重,降低其脂肪含量,并能提高其部分身体素质。由此说明,中学生肥胖可以即早发现其趋势并采用相应的运动处方即时进行预防。据此,为研讨中学生的体质健康和预防肥胖提供一定的参考资料和依据。 相似文献

Obesity is a complex disease with multiple contributing factors.One of the most intensely studied factors during the past decade has been the gut microbiota,which is the community of all microbes in the intestinal tract.The gut microbiota,via energy extraction,inflammation,and other actions,is now recognized as an important player in the pathogenesis of obesity.Dysbiosis,or an imbalance in the microbial community,can initiate a cascade of metabolic disturbances in the host.Early life is a particularly important period for the development of the gut microbiota,and perturbations such as with antibiotic exposure can have long-lasting consequences for host health.In early life and throughout the life span,diet is one of the most important factors that shape the gut microbiota.Although diets high in fat and sugar have been shown to contribute to dysbiosis and disease,dietary fiber is recognized as an important fermentative fuel for the gut microbiota and results in the production of short-chain fatty acids that can act as signaling molecules in the host.One particular type of fiber,prebiotic fiber,contributes to changes in the gut microbiota,the most notable of which is an increase in the abundance of Bifidobacterium.This review highlights our current understanding of the role of gut microbiota in obesity development and the ways in which manipulating the microbiota through dietary means,specifically prebiotics,could contribute to improved health in the host,including musculo skeletal health. 相似文献

Within the Canadian context, the physical activity levels of children and youth in the after school time period has become a source of public health concern. We argue that this concern is informed by broader public health crises, in particular the ‘global obesity epidemic’ and the closely related ‘global pandemic of physical inactivity', and that these so-called ‘crises’ operate as part of a discursive regime that serves to justify after school interventions aimed at increasing the physical activity practices of children and youth. Although the objectives of such interventions are seemingly well intentioned, we suggest that such interventions nonetheless harbor difficult to discern, but potentially pernicious consequences, for the communities in which they are implemented. We focus our attention on the place-specific effects of one Public Health Agency of Canada-funded after school physical activity intervention – After the School Bell Rings (ASBR) – that was implemented in the mostly Indigenous, northern community of Placid, Manitoba. Based on a critical analysis of the ASBR program itself, along with interviews and focus groups with children, parents and recreation providers (n?=?10) from the community of Placid, we contend that the ASBR serves to govern Indigenous recreation at a distance. We argue that when implemented in the place-specific context of Placid, the ASBR functions as part of a broader governmental assemblage composed of loosely connected discourses, institutions, socio-structural conditions and individuals that, when assembled, ultimately serve to govern geographically and culturally distinct communities. We conclude by suggesting that the objectives of broad-based health interventions, such as the goal of increasing after school physical activity levels, should not be universally implemented across diverse locales, but need to account for the diverse, place-specific priorities and needs of the communities into which they are implemented. 相似文献
